Abstract: A spacer device for use with a metered dose inhaler (MDI). The spacer device comprises an aerosol chamber for holding the aerosolized medication sprayed from the MDI. The aerosol chamber comprises a fixed barrel and a sliding barrel. The sliding barrel is in telescoping engagement with the fixed barrel. The sliding barrel slides within the alleyway between the inner shell and outer shell of the fixed barrel. There is an MDI adapter at the distal end of the aerosol chamber, which receives and secures the MDI to the spacer device. In use, the MDI is secured to the spacer device. The sliding barrel is pulled out of the fixed barrel to enlarge the aerosol chamber. After MDI treatment, the sliding barrel is pushed back into the fixed barrel to put the aerosol chamber in compact configuration.

Abstract: Among other things, advertisements are received for brands or products of brands. Criteria for placement of the advertisements are received at online retail sites. The online retail sites are controlled independently from one another. Inventory data for the products at the online retail sites is received and stored. Data about propensities of the consumers to favor one or more of the brands or one or more products of the brands, from activities of consumers on the online retail sites, is stored. Activity data about current activities of the consumers on the online retail sites is received. One or more of the advertisements are placed on pages served to the online retail sites based on the placement data, the inventory data, the propensity data, and the activity data. Conversion data is received indicating that consumers engaged in conversion events with respect to products associated with the brands or products of brands being advertised.

Abstract: Ultrasound transducer assemblies and associated systems and method are disclosed herein. In one embodiment, an ultrasound transducer assembly includes at least one matching layer overlies a transducer layer. A plurality of kerfs extends at least into the matching layer. In some aspects, the kerfs are at least partially filled with a filler material that includes microballoons and/or microspheres.

Abstract: Techniques are provided to allow for efficient data packing under certain coding schemes, e.g., when an enhanced 64/66 encoding scheme is employed. The traditional 64/66 encoding scheme uses idle bytes to pad packets to obtain a packet of fixed size, thereby adding idle overhead to transmitted packets. Accordingly, the techniques eliminate padding bytes and provide for receiving packets by way of a first data link at forwarding device. The packets are transmitted using a scheme that pads the packets to achieve a predetermined packet length. The padding is removed from the received packets to obtain unpadded packets. Data segments of the unpadded packets are concatenated for forwarding in a continuous data stream with a packet delimiter separating each of the unpadded packets. The continuous data stream is encoded using enhanced physical coding sub layer for forwarding over a second data link.

Abstract: An apparatus and method for transmitting ultrasound energy having extended bandwidth and/or suppressed spurious modes for ultrasound transducers is disclosed. In one embodiment, an ultrasound imaging system includes a system chassis for generating ultrasound signals and a transducer assembly coupled to the system chassis having a plurality of stacks each comprised of a plurality of piezoelectric layers having one or more intermediate electrodes interposed between the piezoelectric layers. The assembly further includes a first electrode positioned on a first end of each stack, and a second electrode is positioned on an opposing second end, the first and second electrodes being coupled to the system chassis of the ultrasound imaging system and the intermediate electrodes being coupled to the first or second electrodes.

Abstract: A pickpocket protective wallet includes a wallet body and a DC-power-supply-operated alarm device fastened within the wallet body. A normally closed control switch turns on a sound generating circuit, causing it to produce an audio alarm signal. The control switch is opened as the wallet is put in a pocket, causing the sound generating circuit to stop working. The control switch is closed as the wallet is being taken out of the pocket, causing the sound generating circuit to turn on.

Abstract: A directional indicator made to fasten around the wrist for guiding the user in a predetermined direction, including a magnetized needle attached rotating dial balanced on a pointed pin inside a casing, a needle pointer fastened to a center shaft on the rotating dial, a convex lens covered on the casing over the rotating dial and marked with a fluorescent mark, whereby the needle pointer is maintained in alignment with the fluorescent mark to guide the user toward the predetermined direction.
